A lubricant for cold forging of beryllium and beryllium alloy materials takes number 22 total loss system oil as base oil, integrates various composite additives, and comprises an oiliness agent, an antiwear agent, an extreme pressure agent, an antioxidant, an anti-foaming agent, a reinforcing agent and an assistant. The lubricant for the cold forging of the beryllium and beryllium alloy materials is good in lubricity, stable in composition and performance, easy to diffuse, good in wear resistance, viscosity-temperature characteristic and flush performance, high in extreme pressure, good in coolness and convenient to use and clean, can improve oil film strength in a deformation area, reduces a friction coefficient, can reduce an adhesion phenomenon of a forge piece to a mold and has smaller flow shearing stress. |
